Peripheral facial paralysis (PFP) is a functional disorder of facial muscles primarily caused by damage to the facial nerve or its nucleus, commonly resulting from conditions such as stroke, intracranial infections, or otitis media. The majority of cases are idiopathic facial paralysis, which is associated with factors like cold exposure and seasonal changes. PFP has a rapid onset and is often seen on one side of the face. It can cause paralysis or paralysis of the facial muscles in patients, presenting symptoms such as drooling, facial expression imbalance, inability to close eyes, and limited ability to raise eyebrows, which brings inconvenience to patients' lives and requires timely treatment. Western medicine mostly conducts drug treatment based on the etiology, but there are still some patients with sequelae of PFP. Traditional Chinese medicine theory has unique insights into PFP. It holds that PFP is mostly caused by wind pathogen invading the human body and blocking the circulation of qi and blood in the meridians. Stimulating specific acupoints with acupuncture can promote blood circulation and remove blood stasis, unblock the meridians, dispel cold and dampness, adjust the overall state of the body, improve blood supply to the facial muscles, promote nerve regeneration, and facilitate the patient's recovery. Now, this study aims to further explore the mechanism of acupuncture in the treatment of PFP and the therapeutic effect of acupuncture on PFP at different times, providing a basis for improving the therapeutic effect of acupuncture on PFP and accelerating the recovery process.
